It is a waste of energy for the oil-w ell motor to work in full load while the oil storage under the ground was empty or insufficient. To solve this problem, the paper presents a kind of no timing optimizing auto-controller of oil-well motor, to which the SCM control technology has been applied. The auto-controller takes MCS – 51 series SCM( 80C552) as its key component, the electric- current sensor as its direct checking part. Furthermore, the designers have taken into full consideration field anti-jamming measures during the designing process. Feedback from the fieldwork indicates that the controller is reliable and energy-saving. The consumption of electricity can be reduced by 30%.
The oil motor MCU development of control technology without timing automatic controller, can realize the overload, the oil motor of light load, detection and intermittent heavy-duty automatic optimization of switching control, so as to realize the automatic optimization of mining and electricity saving of oil energy, in order to meet the needs of modern production requirements.
This paper first introduces the oil motor causes no automatic timing controller generates and the research direction. Then explains the implementation of the overall scheme design and selection of scm. And working conditions of how to detect the oil motor problems, the selection of current transformers. The hardware design of the controller, the software design in detail. Analysis of energy saving, fully demonstrated the time controller can meet the requirements of modern production methods. And make a summary of the design.
Key words: oil-well motor SCM( 80C552) auto-controller
